HP Pavilion 15-n209TX Display :: Function Keys - F2 And F3 Not Working?

May 14, 2014

I purchased HP Pavilion 15-n209TX Laptop this year and the functions keys were working properly. But, later on from 10th of May 2014, they are not working! I checked whether there was a software due to which it was happening, but, I didn't install any kind of software which can harm the functioning of the keys. I am really struggling with very low brightness. The latest thing I did was - windows update - which installed the following softwares
 
Microsoft Silverlight 
 
Also, I installed HP Quick fix. 
 
Whenever I press F2 or F3, it just shows the slidebar (it doesn't go up and down though) and when I click on the top of the slidebar, nothing happens again. I also tried to go to the brightness option in the Windows Mobility Centre and tried to adjust the brightness - but nothing is happening.

HP Pavilion G6-2224CA :: Function Keys Working In Reverse

Jul 25, 2010

The function keys on my keyboards are working in the opposite manner. Whenever I press any of the keys from F1 to F12 they perform the multimedia actions or their enhanced action. For example, if I press the F2 key the brightness of my laptop screen would lower. It should not work like this. I should be pressing Fn+F2 for the brightness of my screen to lower. The problem here is that I can't use Alt+F4 to close windows because its reversed, I instead have to press Alf+Fn+F4.
 
I have already search for an answer online and I can only find that NumLock is supposed to be locked. But, it's a laptop - I have no such key.

Lenovo P/Y/Z Series :: Reversing Function Of All F Keys - Z500

Oct 10, 2012

The default behavior of F1 through F12 keys on the z500 are set to perform laptop functions like mute, turn sound or brightness up and down and so on.
 
Is there a way to reverse the way F1, F2.. F12 keys work, so they work like on any other regular keyboard.
 
I use the basic functionality of the F-keys all the time, when renaming files, searching and so on, and I would like to be able to use them without having to press "fn" every time.

Lenovo P/Y/Z Series :: IdeaPad P400 - Reverse Function (Fn) Keys

Feb 24, 2013

I recently purchased an Ideapad P400, and I have noticed that the default for  the keys where  F1 and F2, etc. usually are, are now the mute and volume buttons.  To access the F1, F2....F12 keys, you now have to press Fn + your desired F key.  
 
While I understand many people probably find this useful, I play several games where these keys are essential, and it makes playing the games nearly impossible to play if you have to hold down the Fn key in addition to the desired F key.  So my question is, is it possible to reverse the Function keys?  I would much rather press Fn + F1 to mute than have to press press Fn + F1 to access F1.

Lenovo G710 B / G Series :: Function Keys Do Not Display Action On Screen

Mar 8, 2014

I recently downgraded my G710 from Windows 8 (which it came with), to Windows 7.  The only issue I've noticed is that it does not display anything on screen when you use the function keys, such as the volume up or down, or bright ness up or down.  The keys work, but it would be nice to see on screen that my volume is set at 2% vs say 100% when I'm turning it up or down.

Lenovo M490 C/E/K/M/N/V Series :: Could Not Find Software That Controls Function Keys

Dec 22, 2013

I've bought Lenovo M490s notebook one week ago without OS. I've installed Windows 7 Professional x64 retail.First of all I could not find software that controls Function keys. After installing every driver and software from support page (M490s) my function keys just doesnt work except Fn+F1 sleep, Fn+F2 turn off the screen, Fn+F6 disable touchpad and play buttons. Also no information was displaying on the screen after pressing such buttons - no volume and brightness level.
 
After doing some research I've found and installed Hotkey Features Integration from Lenovo M490 (without S) support page. Every function key is started to work, information on the screen also begin to display (volume and brightness level).Now I spotted a huge problem, after 3 or 4 hibernation volume and brightness keys (fn+up,down,left,right) just stopping to work!!! Fn+F1-F12 combinations are working normal. Then after reboot brightness and volume keys are working again!!

Sony :: SR-430J W7 64bit Function Keys

Dec 17, 2009

got my SR-430J. it's probably an older model since it came with Windows Vista...

So first thing I did was did a clean install of Windows 7 Enterprise (a RTM version, and the genuine key is applied so it should be the same as the market version)

I can't for the last 3 hours get the brightness key working... >_> the audio key works but not the brightness... can anyone offer a solution? If not is there another way through windows to change brightness on a laptop screen?

I followed several guides here.. installing the shared library, firmware parser etc... still doesn't work ;x

I am using Windows 7 Enterprise 64-Bit Japanese...

Sony :: FW Function Keys Don't Work After Clean Install

Sep 16, 2009

I tried doing a clean install for my friend's Vaio VGN-FW463J/T. I left the hidden Sony recovery partition intact just in case something went wrong. I used a retail Vista x64 sp1 disk and installed it just fine. Then I started installing the drivers, but some of them wouldn't install. The Sony Shared Library starts to install, but then just disappears and doesn't say that it finished installing. The Sony notebook utilities doesn't install because I can't get Shared Library to install. A prompt says that it only works on vista, a message which causes me great confusion. But I can get the Sony Firmware Extension Parser Device Driver to install correctly. The problem is that the fn keys don't work.

And the Intel SATA Driver Registry Patch doesn't install. I think it's because I don't have the original drivers installed, or is this it? I'm missing something huge, aren't I?

Sony :: How Do I Get Function Keys To Work On SR420 After Clean Windows 7 Install

Nov 4, 2009

I did a clean install of Windows 7 and I was surprised that almost everything is working out of the gate. There are only a few bugs that I've noticed.

1.) The Fn functions in the F-keys don't work. Which driver do I need for that?

2.) Same thing goes for the Mode - - - - - Settings keys above that. Which driver fixes that?

3.) In the device manager I have and unknown "Base System Device" with the Location of "PCI bus 7, device 3, function 2". What is this/How do I fix it?

4.) The touchpad doesn't scroll. I tried installing the driver from the Sony eSupport page, but it failed. (I reinstalled and rebooted and it's working)

And not a bug, but just a straight up question...
5.) Should I install Sony Shared Library? Do I need it for anything? I really don't plan on installing any of the programs that came pre-installed with Vista, unless it's necessary.

I've tried all sorts of things - uninstalling and uninstalling the keyboard drivers in Device Manager, reinstalling the BIOS, unchecking all the boxes under the accessbility options, scanned the computer for malware...but nothing seems to work.
 
I've also installed Windows 8.1 and replaced my HDD with an SSD...

HP G72 :: How To Change Default Function Keys

Dec 20, 2010

I much prefer to use the function keys AS FUNCTION KEYS. I don't want the default to be fast forward or rewind or stop or sound options. I want f2 to be f2 (edit excel cell) and so on. Currently I press fn EVERY time. It's annoying.
 
Is there a way of changing the defualt key to be what was originally intended? HP has made finding this information impossible so far.
 
Notebook computer keyboard on a HP G72.
